It was found that eosinophil levels were lower in individuals with severe strongyloidiasis, as compared with those with asymptomatic individuals.[26] In another study, it was seen that approximately 75% of patients with chronic strongyloidiasis have peripheral eosinophilia or elevated total IgE levels.[12,15] Therefore, it is assumed that eosinophil levels may play definitive role in preventing and combating S. stercoralis infection. This evidence concerns the gene IGHE and strongyloidiasis.
